FAQs about EAp2 :

Do the required savings for this prerequisite (and credit) need to come only from building energy, or also process loads?

Our project doesn't have enough energy savings to earn the prerequisite. Can we get there by incorporating onsite renewables?

Our proposed design has insulation R-values that are below those prescribed by ASHRAE 90.1-2010. Can we still meet the prerequisite?

NC-v4 EAp2:Minimum energy performance

Demand Control Ventilation

Can you take credit for occupancy sensors that control HVAC systems? I am thinking probably not for system operation E.g setbacks, agree? But I am unsure for the ventilation. It seems a bit waffly trying to determine when the spaces are "occupied" as technically they are 24/7 but occupant will come and go during that time. Should the baseline be 24/7 for ventilation and the proposed as per expected design for ventilation taking account occupancy sensors...? Thanks

You can do so as an exceptional calculation. See the Appendicies of the Advanced Energy Modeling Guide for LEED for an example. Make sure you can defend the schedule adjustment associated with the occupancy patterns..
